meml er which either seats upon the upper surface of the looely of the mold or is located directly shove the mold. For ccrtam kinds of were. or molds it is necessary or desirable to have the charge assume a low squat shape at the lower end Of 'il15 mold before the molding operation. ..1 quently the mold cavity is of such shape and proportion as to render it difiioult to deliver mold charges-into it and yet have such charges assume the proper shape after do livery-x. This is particularly true of certain press molds in which when the charge emerges from the guide as used at present, there is a tendency for it to fall or skimp toward one side or the other and out of trsl relation with the pressing plunger, so that the glass in being forced up into the annual space between the plunger and the mold Wall is higher on one side than on the other and must be distributed around the plunger after contact with the mold ring. This is not only liable to cause, unequal wall thickness of the were, but imposes a severe sidewise strain hctweeu the mold and the plunger, tending to wear these elcmcols excessively, particularly where the plunger I bears against the mold riu The object of this invention is to deliver a mold charge in a compact and symmetrical mass at the bottom of the mold and couccw trio therewith so as to secure o uniform distribution of the glass around the plunger throughout the pressing operation.

'lhisis accomplished by projectiiig the funnel, deflector or other guiding means into the mold cavity so that s charge emerging therefrom will be de gosited directly in the bottom of themold cavity and in on uc-. curutely centered position Without contact with the upper portion of the walls of the mold. In some instances, particularly Where relatively long mold cliargesore being delivered to the mold it is desirable to project the guiding member sufficiently for into the mold cavity that the ois'tzincc between the lower of the guiding mcm-- her and the hot Mm. oi the mold cavity is less than the length of the mold clisrge. ll so side or the other of the mold.

This extension is preferably also flared slightly, as indicated at lei, so as to prevent the glass from Wedgizig in the lower portion thereof after passing through the restricted portion of the funnel. The extension 14. is of such length, and is projected sufiicieutlv far into the mold cavity, that it will reinsiii in later ally supporting eiigzi euient with s mold chm-gs after the latte-i deposited lllw ill? bottom of the cavity, and will prcvcnt the ugiycr portion oi the mold charge from tilting laterally or slumping ovcr against ion liter mold charge has liecri delivered into the mold and allowed to settle sutliciently, the funnel is withdrawn from the cavity and the mold ring so as to permit the entrance of a pressing plunger, not shown, to perform the pressing operation. The guiding member may be moved aside by suitable mechanism, not shown, in cases where the mold is located permanently at a lixcd pressing; station, to permit the plunger to descend into the mold. When the device cmljiodicd in a machine having a moving mold table, it is only necessary to raisc the tunnel. sutlicicntly to allow the mold and mold rinc to pass on to its succecdinzy pressing st;.ti0n.

While I have shown and described the invention as being applied to a glass pressing machine, it should be understood that it may also be utilized in glass blowing machines,

and particularly the narrow neck type in which the mold charge is lcd to an inverted parison mold and blown thcrcin.

The particular embodiment of the invention illustrated and described has been selected by way of example only, and it is to be understood that Ylil'lUdS modifications,

arrang'cnmits, and combinations may be employed in t'ultilliin the spirit of the invcntion as dctincd in the claims.

l claim as my invention:

l. in combination with a glass shaping mold, a guiding member adapted to be projected into the mold cavity in spaced relation with the walls and bottom thereof to deposit: a mold charge in the bottom of said cavity and prevent contact between the charge and the upper wall ot said mold.

52. in combination with a glass shaping mold, a guiding member adapted to be projccted into the mold cavity to deposit a mold charge in the bottom of said cavity and provide lateral support to the upper .cntLof said charge until the lower portion thereof conforms to the configuration of the bottom of said cavity, said member being spaced from the bottom of said carity to permit the charge to tlow thcrcbcneath and into contact: with the lower said cavity.

portion of the walls of marrow In combination with a glass shaping mold, a guiding member adaptedto be projectedinto a mold cavity to deposit a moi charge in the bottom of said cavity and to prevent contact between said charge and the upper portion of the wall of said mold cavity, and to remain in contact with the upper portion of said charge until the lower portion thereof commences to settle laterally into said mold, said member being spaced from the bottom of said cavity a distance sutlicient to permitthe charge to settle out of contact with said member.

In combination with a glass shaping mold, a guiding member adapted to be projected into the mold cavity to deposit a mold charge in the bottom of said cavity, and to prevent contact between the mold charge and the walls of the upper portion of said cavity and to remain laterally in supporting engagement With said charge until the same has commenced to settle into the mold, the distance between the bottom of said member and the bottom of said cavity being greater than the height of the mold charge after it has settled in said cavity.

5. In combination with a glass shaping mold, a funnel adapted to be projected into the mold cavit and in spaced relation to the sides and ottom thereof to deposit a mold charge in the bottom of said cavity portion thereof, said funnel having flared upper and lower portions and constricted intermediate portions.

(5; In combination with a glass shaping mold, a funnel adapted to be projected into the mold cavity and in spaced relation to the sides and bottom thereof, to deposit mold charges in the bottom of said cavity without contact with the walls of the upper portion therml, the internal diameter of the en tram wand exit cnds of said tunnel being greate than that of the intermediate portion. v
